Influencia de la temperatura y el volteo durante el almacenamiento en los parámetros de incubación de huevos fértiles

The influence of temperature and turning frequency during storage on the incubation parameters of fertile eggs was evaluated. A completely randomized design (CRD) with a 2x4 factorial arrangement was used, where the factors under study were: Factor A: storage temperatures of 16 °C and 18 °C, and Factor B: turning periods of 6, 12, 18, and 24 hours. Eight treatments were established with four replicates each, using a total of 1600 eggs. The variables evaluated were fertility, infertility, embryonic mortality (early, intermediate, and late), egg weight loss, first and second-grade chick production, hatchability, and chick weight performance relative to egg weight. Significant differences were found for Early Embryonic Death (EED) and Late Embryonic Death (LED). Early embryonic death (EED) was more frequent in eggs turned every 18 hours (stored at both 16°C and 18°C), while the highest META values were reported in eggs stored at 16°C with turning every 12 hours. A trend toward improved hatchability (78.5%) was observed in eggs stored at 18°C with turning every 12 hours, correlating with a higher number of first-hatched chicks under these same conditions. It is concluded that temperature and turning frequency during storage affect early and late embryonic mortality, but do not significantly influence chick production or chick weight yield.
